Problems solved by technology

However, the existing patented technology has disadvantages such as high price (such as Japanese science), complicated operation, etc.
For example, although a foreign patent (US5635138) can realize the test function of in-situ battery XRD, it has too many assembly parts, complex design, and difficult application, which is not suitable for the configuration of mainstream domestic diffractometers.
[0003] Although some other domestic patents (such as CN100373168C, CN102435625A, CN203434214U) can also perform in-situ battery measurement of XRD, a common feature is that the compactness of the measurement electrode part is not good, or that the battery material and the electrode of the collector are poor. The contact is not good enough, which affects the conductivity, and then affects the phase transition process of the battery material, and cannot really realize the research significance of in-situ battery accessories

Description

technical field [0001] The invention relates to the field of battery measurement, in particular to an X-ray diffractometer in-situ battery accessory, a heating device, a cooling device thereof, and a method for measuring lithium battery materials using the X-ray diffractometer in-situ battery accessory. Background technique [0002] Lithium battery material is one of the very important battery raw materials at present. The development of lithium battery material is a very important research direction in recent years. X-ray diffraction is an indispensable and important means for lithium battery material research. In situ battery attachments that can perform X-ray diffraction have been the focus of this technology. Using the XRD (X-ray diffraction) in-situ battery accessory, the phase and structure of the battery material during the charge-discharge cycle can be observed in real time, avoiding the deviation of the experimental results caused by static and quasi-static measurem...
